I used to have something like this on my profile but, I don't know,
it got lost for some reason. So, here we go again:

Dear everyone,
I just want you to know that you are amazing and absolutely worthy
of having a satisfying life. Chances are, you joined this site for
obvious reasons. And even if you never find a match for yourself
here (or anywhere) you deserve to be happy. Single or not. Easier
said than done, I know. But true, regardless.
